■ Industry standard configurations

❐ Operating voltages:

Features

■ 64-Kbit nonvolatile static random access memory (nvSRAM)

internally organized as 8 K × 8

❐ STORE to QuantumTrap nonvolatile elements initiated

automatically on power-down (AutoStore) or by using SPI

instruction (Software STORE) or HSB pin (Hardware

STORE)

• CY14MB064Q: V_CC= 2.7 V to 3.6 V

• CY14ME064Q: V_CC= 4.5 V to 5.5 V

❐ Industrial temperature

❐ 8- and 16-pin small outline integrated circuit (SOIC) package

❐ Restriction of hazardous substances (RoHS) compliant

Functional Overview

❐ RECALL to SRAM initiated on power-up (Power-Up

RECALL) or by SPI instruction (Software RECALL)

The Cypress CY14MX064Q combines a 64 Kbit nvSRAM with a

nonvolatile element in each memory cell with serial SPI interface.

The memory is organized as 8 K words of 8 bits each. The

embedded nonvolatile elements incorporate the QuantumTrap

technology, creating the world’s most reliable nonvolatile

memory. The SRAM provides infinite read and write cycles, while

the QuantumTrap cells provide highly reliable nonvolatile

storage of data. Data transfers from SRAM to the nonvolatile

elements (STORE operation) takes place automatically at

power-down (except for CY14MX064Q1A). On power-up, data

is restored to the SRAM from the nonvolatile memory (RECALL

operation). You can also initiate the STORE and RECALL

operations through SPI instruction.

❐ Support automatic STORE on power-down with a small

capacitor (except for CY14MX064Q1A)

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1million STORE cycles to QuantumTrap

❐ Data retention: 20 years at 85 C

■ High speed serial peripheral interface (SPI)

❐ 40-MHz clock rate SPI write and read with zero cycle delay

❐ Supports SPI mode 0 (0,0) and mode 3 (1,1)

■ SPI access to special functions

❐ Nonvolatile STORE/RECALL

❐ 8-byte serial number

❐ Manufacturer ID and Product ID

❐ Sleep mode
